The Correlation between Insertion Depth of Prodisc-C Artificial Disc and Postoperative Kyphotic Deformity - Clinical Importance of Insertion Depth of Artificial Disc Do-Youl Lee, Se-Hoon Kim, Jung-Keun Suh, Tai-Hyoung Cho, Yong-Gu Chung Department of Neurosurgery, Korea University College of Medicine, Seoul, Korea Objective: This study was designed to investigate the correlation between insertion depth of artificial disc and postoperative kyphotic deformity after Prodisc-C total disc replacement surgery, and the range of artificial disc insertion depth which is effective in preventing postoperative whole cervical or segmental kyphotic deformity. Methods: A retrospective radiological analysis was performed in 50 patients who had undergone single level total disc replacement surgery. Records were reviewed to obtain demographic data. Preoperative and postoperative radiographs were assessed to determine C2-7 Cobb’s angle and segmental angle and to investigate postoperative kyphotic deformity. A formula was introduced to calculate insertion depth of Prodisc-C artificial disc. Statistical analysis was performed to search the correlation between insertion depth of Prodisc-C artificial disc and postoperative kyphotic deformity, and to estimate insertion depth ofProdisc-C artificial disc to prevent postoperative kyphotic deformity. Results: In this study no significant statistical correlation was observed between insertion depth of Prodisc-C artificial disc and postoperative kyphotic deformity regarding C2-7 Cobb’s angle. Statistical correlation between insertion depth of Prodisc-C artificial disc and postoperative kyphotic deformity was observed regarding segmental angle (p
